jquery cookie for css style switcher

Question

I'm trying to make a stylesheet switcher in jquery with a success but when I try to save the changes in a cookie using jquery.cookie plugin, it doesnt work..

here's the jquery code:

$("#theme-cp ul li").click(function () {
    var $pattern = $(this).css("background-image");
    $("body").css("background-image",$pattern);
    $("#main-wrapper").css("background-image",$pattern);
    $.cookie('background',$pattern);
    alert($.cookie('background'));
});

the alert is for a check but it doesnt work....

I read the doc: github.com/carhartl/jquery-cookie $.cookie('the_cookie', 'the_value'); var $test = $.cookie('the_cookie'); alert($test); doesnt work as well.. — Dvir H

I have recently done the same thing, i got it working, thought i'd share my code with you.

jsFiddle

jQuery

//If Cookie isn't blank (i.e. do we have a cookie set at all?)
if($.cookie('colour')!='')
{
    $('body').addClass($.cookie('colour'));  //set the body to the cookie colour
}

$('#accessibility-colours a').each(function(index)
{
    $(this).click(function(e)
    {
        e.preventDefault();

        switch(index)
        {
            //black text white background
            case 0:
                $('body').removeClass($.cookie('colour'));
                $('body').addClass('blackText-whiteBackground');
                $.cookie('colour', null);
                $.cookie('colour', 'blackText-whiteBackground',{ expires: 7, path: '/' });
            break;

            //black text yellow background
            case 1:
                $('body').removeClass($.cookie('colour'));
                $('body').addClass('blackText-yellowBackground');
                $.cookie('colour', null);
                $.cookie('colour', 'blackText-yellowBackground',{ expires: 7, path: '/' });
            break;

            //black text pink background
            case 2:
                $('body').removeClass($.cookie('colour'));
                $('body').addClass('blackText-pinkBackground');
                $.cookie('colour', null);
                $.cookie('colour', 'blackText-pinkBackground',{ expires: 7, path: '/' });
            break;

            //blue text white background
            case 3:
                $('body').removeClass($.cookie('colour'));
                $('body').addClass('blueText-whiteBackground');
                $.cookie('colour', null);
                $.cookie('colour', 'blueText-whiteBackground',{ expires: 7, path: '/' });
            break;

        }
    });

CSS

html, body                              {font:0.9em/1.1em "Arial", sans-serif}

/* Accesibility Icons */
#accessibility-colours                  {margin:0px; overflow:hidden;}
#accessibility-blackWhite               {background:url(../images/design/icon-accessibility-blackWhite.gif) 0 0 no-repeat}
#accessibility-blackYellow              {background:url(../images/design/icon-accessibility-blackYellow.gif) 0 0 no-repeat}
#accessibility-blackPink                {background:url(../images/design/icon-accessibility-blackPink.gif) 0 0 no-repeat}
#accessibility-blueWhite                {background:url(../images/design/icon-accessibility-blueWhite.gif) 0 0 no-repeat}

    #accessibility-colours a            {float:left; display:block; margin:6px 0 0; padding:4px; border:0; width:16px; height:16px;}
    #accessibility-colours a span       {margin:0; padding:0; position:absolute; top:-9999px; left:-9999px;}


/* Colours to be set for accessibility choice */
.blackText-whiteBackground              {background:white; color:black}
.blackText-yellowBackground             {background:yellow; color:black}
.blackText-pinkBackground               {background:pink; color:black}
.blueText-whiteBackground               {background:white; color:blue}

HTML

<div id="accessibility-colours">
        <a id="accessibility-blackWhite" href="#" title="Black text / White background"><span>Black text / White background</span></a>
        <a id="accessibility-blackYellow" href="#" title="Black text / Yellow background"><span>Black text / Yellow background</span></a>
        <a id="accessibility-blackPink" href="#" title="Black text / Pink background"><span>Black text / Pink background</span></a>
        <a id="accessibility-blueWhite" href="#" title="Blue text / White background"><span>Blue text / White background</span></a>
    </div>

    <h1>This is the H1 tag</h1>

    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Etiam facilisis nibh sed tortor blandit interdum semper leo ullamcorper. 
    Pellentesque gravida hendrerit accumsan. Mauris pretium blandit augue, suscipit ultricies libero aliquam sit amet. Aliquam egestas eleifend augue,

    Vestibulum nisl dolor, aliquam et posuere ut, tincidunt sed mi.</p>

I'm sure its a working code but there has to be a simpler way to do what I need.. take a look at my code.. it's really simple but somehow it doesnt work :\
